The first thing that a doctor will do so they can determine if you are lactose intolerant or not is to ask you some questions about your symptoms after eating or drinking dairy products that contain lactose.

The symptoms of lactose intolerance are things such as Abdominal pain; Flatulence; Diarrhea etc.

If you experience abdominal pain after eating dairy products or drinking milk that contains lactose then you're likely lactose intolerant.

Your doctor will also usually do a blood test to determine for sure if you are lactose intolerant or just allergic to dairy.

Some people are just allergic to dairy and are not lactose intolerant.

But the blood test will show whether or not you're lactose intolerant.

Two hours before the blood test your doctor will have you drink a liquid which will help measure the amount of glucose in your bloodstream.

That can determine whether or not you're lactose intolerant.

The different types of lactose intolerance are.

Developmental lactose intolerance.
Secondary lactose intolerance (due to illness or injury).
Congenital or developmental lactose intolerance (being born with the condition).
Primary lactose intolerance (normal result of aging) This is the most common type of lactose intolerance.

The difference between a milk allergy and Lactose Intolerance is a milk allergy is the immune systems reaction to the proteins that are found in milk and the lactose Intolerance is the body's inability to digest the Lactose.

You can be allergic to milk and have a milk allergy but not be lactose intolerant.

Lactose Intolerance and a milk allergy are different.

The lactose intolerance is when you cannot tolerate the lactose while a milk allergy is when you're allergic to the milk.

You can sometimes be allergic to milk but not cheese or other dairy products.

In that case you're most likely just Lactose intolerant and don't have a milk allergy.

You may be able to eat a small amount of some foods with lactose.

For example, you may be able to eat cheese or yogurt, but not drink milk.

Aged cheeses, like cheddar and Swiss, have very little lactose.

Or you may be able to eat some prepared foods.

If you have a milk allergy you usually cannot eat cheese because cheese contains milk.

Cheese is made from milk and is dairy so if you have a milk allergy you'll have to avoid cheese or it can trigger your milk allergy symptoms.

Someone with a dairy allergy can eat eggs as eggs are not dairy.

Dairy is foods made from milk including the  milk and eggs do not contain dairy or milk.

Eggs are not a dairy or dairy product because dairy refers to milk that is made from the breast or mammary gland of the breast.

Foods that are made from milk are dairy products such as cream, butter cheese and milk itself.

Hotdogs do not have dairy in them as hot dogs are basically just a mixture of meats although beef hotdogs are strictly beef but other hotdogs can contain beef and chicken and other meats mixed together.

Oreos do not contain dairy and Oreos are dairy free.

If you have a milk allergy you can eat Oreo cookies without an issue.

Oreo cookies are also gluten free as well.

Bread such as white bread is not considered dairy as white bread is dairy free although some types of bread may have dairy or milk in the ingredients.

Most bread is made from yeast, flour, water, and salt, so it would be suitable for vegans.

Unfortunately some commercially sold breads (e.g. sold at supermarkets) contain dairy such as whey (a milk protein) or eggs as fillers or stabilizers and those breads would not be considered vegan (or plant-based).

Donuts do have dairy in them.

The ingredients in donuts are oil, sugar, salt, eggs, yeast, milk, butter and flour.

Milk, eggs and butter are common ingredients that are used in recipes in bakeries including donuts.

If you have a milk allergy then you want to avoid donuts.

A milk allergy can cause joint pain because when you have a milk allergy the milk when consumed can lead to pain in your joints and inflammation in your joints.

The inflammation and pain in your joints when you have a milk allergy is caused by an increase in histamine and other chemicals in the body.

To diagnose a milk allergy a skin test can be done.

During the skin test for a milk allergy your skin is pricked and exposed to small amounts of the proteins found in milk.

If you're allergic, you'll likely develop a raised bump (hive) at the test location on your skin.

Allergy specialists usually are best equipped to perform and interpret allergy skin tests.

A milk allergy is an abnormal immune system response to the consumption of milk and milk products.

Milk allergies and dairy allergies are also common in children.

Symptoms of a milk allergy or dairy allergy include hives, vomiting, stomach cramping, bloating, digestive issues.

Although both require the elimination of dairy products from your diet, and some of the symptoms overlap, lactose intolerance and dairy allergy are not the same thing.

Lactose intolerance is a problem of the digestive system; dairy allergy is a problem of the immune system.

If the person with a milk allergy drinks or eats a product that contains milk, the body thinks these proteins are harmful invaders.

The immune system responds by working very hard to fight off the invader.

This causes an allergic reaction. Milk is among the most common foods that cause allergic reactions.

Even though milk allergy treatment is not a cure, it can certainly lessen the impact of consuming milk and milk products.

As stated above, both children and adults can suffer from milk allergies.

And while it may be more prevalent in children, there is no “age range” immunity.
